Virtual domains with Tomcat
How can I get Tomcat to recognize virtual domains? This is trivial with
Apache and I can get Apache to fetch the correct jsp but I cannot get timcat
to process it. If I turn off tomcat, apache sends the jsp source. If I turn
tomcat on, I get the error 404 page
workers.properties:

Yes, AFAIK.
As I understand it, the JK/JK2 connectors are pipelines, not pre-or post-
processors. They send the request from Apache to Tomcat. When Tomcat
receives the request, it is as if Apache doesn't even exist. Tomcat acts
the same way it would act if using Tomcat stand-alone. I could be wrong,
but I've never been able to successfully setup a virtual hosting
configuration without defining my virtual hosts in both Apache's httpd.conf
and Tomcat's server.xml. If there's a shortcut, I'd love to see it.

When you use virtual hosts on apache2 with mod_jk2 does Tomcat have to
have the same virtual hosts defined in it's server.xml file?

Re: Virtual domains with Tomcat

Yes. In general, for every Apache ServerName, you need a corresponding
Host entry in Tomcat's server.xml.
The Apache connectors are just pipelines, they do not do any work on behalf
of Tomcat. Thus, when Tomcat receives the request, it has to do the same
sort of host header processing that Apache has to do. If Tomcat cannot
find a Host entry that corresponds to the HTTP Host Header it is receiving
on the request, it will default to the host name listed in the defaultHost
parameter in server.xml. Apache does the same thing...if it can't find a
VirtualHost to match the host header, it defaults to the global
VirtualHost, or rather the global ServerName.
The syntax for defining a virtual host in Tomcat's server.xml is different
than Apache's httpd.conf, but the principles and concepts are the same.

Anything in the logs?
I'm not totally sure, but I think you need to match VHosts in your Apache and your Tomcat. I'll be testing exactly that today with mod_jk2, Apache 2.0.46 and Tomcat 4.1.24. For mod_webapp it is definite - you need:
<Service ...>
<Connector ...>
<Engine ...>
<Host name="my-vhost.domain.com" ...>
<Context docBase="..." path=".."/>
....
</Host>
</Service>
I think the same applies to all other connectors: mod_jk, mod_jk2 and HTTP.
Nix.

That works. Thanks.
I had to remove the <Context ... /> -- It caused tomcat fail. Howewer, it
seems it is not necessary.

Re: Virtual domains with Tomcat

It is trivial in Tomcat as well.
For each Apache ServerName, you will need a corresponding Host entry in
Tomcat's server.xml. Make sure each virtual host in Tomcat's server.xml
has its own appBase.
For the VirtualHost you posted:
<Host name="dookoo.totalflood.com" appBase="/var/jakarta/totalflood">
<Context path="" docBase="ROOT" />
</Host>
...or something very similar. Put your JSPs in
/var/jakarta/totalflood/ROOT. Make sure there is a directory called
/var/jakarta/totalflood/ROOT/WEB-INF. Delete your Directory entry that
allows all, and instead add a Directory entry that restricts WEB-INF and
META-INF. This is all covered in the docs for Host and for Context. An
example of what configuration for Apache looks like, for a virtual host
named "localhost", is here:
